Kugelfischer injection (also called System Kugelfischer) is the name for a mechanical fuel injection (MFI) pump. It was produced by FAG Kugelfischer and later by Robert Bosch GmbH [ 1 ] Derived from diesel pumps from the early 1960s, the Kugelfischer system was a mechanical injection pump for performance vehicles.
Inline diesel injection pump. Earlier diesel pumps used an in-line layout with a series of cam-operated injection cylinders in a line, rather like a miniature inline engine. The pistons have a constant stroke volume, and injection volume (i.e., throttling) is controlled by rotating the cylinders against a cut-off port that aligns with a helical ...
The German direct-injection systems were based on diesel injection systems used by Bosch, Deckel, Junkers and l'Orange. [35] By around 1943, the Rolls-Royce Merlin and Wright R-3350 had switched from traditional carburettors to fuel-injection (called "pressure carburettors" at the time), however these engines used throttle body manifold ...
Common rail fuel system on a Volvo truck engine. In 1916 Vickers pioneered the use of mechanical common rail systems in G-class submarine engines. For every 90° of rotation, four plunger pumps allowed a constant injection pressure of 3,000 pounds per square inch (210 bar; 21 MPa), with fuel delivery to individual cylinders being shut off by valves in the injector lines.

EDC injection inline pump. The mechanical fly-weight governors of inline and distributor diesel fuel injection pumps used to control fuel delivery in diesel engines under a variety of engine loads and conditions could no longer deal with the ever-increasing demands for efficiency, emission control, power and fuel consumption. These demands are ...
Mechanical fuel injection, 'K' stands for German: "Kontinuierlich", meaning continuous.Commonly called 'Continuous Injection System (CIS) in the USA. K-Jetronic is different from pulsed injection systems in that the fuel flows continuously from all injectors, while the fuel pump pressurises the fuel up to approximately 5 bar (73.5 psi).
